Chinese chisels

Using a Chinese chisel to Clean up a cramp pocket.

I have had these chisels for over six years now. Quite different from the British style of chisel that I am used to.  I wasn't sure about these at first, but the more I use them, the more I like them.

Easy to sharpen. Rather lightweight, and the steel is slightly softer than my other chisels.  The narrowest ones can bend when used to lever with, so they are not suitable for heavy duty work.  However, they are good for paring with, and they hold their edge for a surprisingly long time. The fishtail pattern is useful for getting into tight areas, so they are ideal for cleaning up these cramp pockets.

The handles could be a more ergonomic shape, and oddly they are all the same size. The size of a tool handle is usually proportionate to the size of the blade. But having said that, they seem to be fine in use, so I will probably not make replacement handles for them.

These Chinese chisels are very nice to have in addition to my regular chisels, and it would also be nice to have a more robust version of these for heavy duty work.

Chinese seal

Many thanks to my friend Jason Tsang, of White Horse Tai Chi, for bringing me this beautiful Tigersden seal back from Hong Kong. It was specially made by hand, and features a carved Tiger on the top!

The same characters as the Tigersden Registered Trademark that is branded onto the blades. Except that the mujian use a slimmer seal, because those proportions are more suited to a narrow blade.

Although greatly feared in China, the tiger was symbolic of strength, courage and military prowess. It was also synonymous with protection, because the character for Tiger, Hu, has the same sound as the character for Protection. Tigers have been used as symbolic and talismanic images since ancient times, and have been particularly popular as talismans on hats and shoes for children. In the Ming and Qing dynasties the Tiger was used to denote the 3rd and 4th military officer ranks.

The second character on the seal is Xue, which in this case means den. However, it also means cave, so the name Tigersden, is actually a play on my own family name. This is quite fitting because Chinese culture has a long tradition of using puns, rebuses, and homophones.

Brass inserts

The first post has a mujian with inserted brass balance weights and inserted brass seven stars decoration. However, achieving a clean tight join between the brass insert and the wood, is actually more difficult than one might imagine.

The ends of the inserts need to be chamfered in order to ease them into the hole, but an uneven handmade chamfer will cause them to skew to the side. The brass also needs to be inserted very carefully. Hammering a brass insert into a hole can force it to one side, compressing the wood and causing gaps to appear.

The quickest and most accurate method for truing up and chamfering the brass rod is to use an engineering lathe.

Not many woodworkers have engineering lathes, but brass is a fairly soft metal to work with, so if there isn't an engineering lathe available, it is possible to do this with the brass held in a woodturning lathe, and using a file to do the shaping.

Once trued up, the brass needs to be inserted into the wood. This is best done using an even pressure in direct line with the hole. Ideally, an arbor press would be used, but a drill press will do this operation adequately. I still haven't got around to purchasing an arbour press. In the following picture, the brass rod is pushed into the wood by a length of stainless steel bar. The masking tape is used as a depth stop.

Double cord grip wrap

I have been making mujian and mudao for well over 10 years, and I have been doing grip wrapping for almost as long, but this is the first time that I have had the pleasure of doing a double cord wrap.

This wrapping is done in the same way as a standard grip wrap, but it uses a narrower cord, twice as long, and folded in half. The cord in this case, is traditional Chinese braided cotton. Twisted cords are also authentic for these wraps, and can be found on antique Chinese jian and dao.

As one might expect, this type of wrapping is much more fiddly and time consuming to do, than a standard wrap.  As the wrap proceeds, the cords tends to wind around each other, leading to unwanted tension and crossed cords. So it is very important to be methodical and to double check each loop before continuing on to the next one.

Double cord grip wrap

The finished grip wrap feels quite solid to the touch and less compressible than standard wraps. As the the cord diameter is only 1mm, the crossovers have a fairly low profile. As well as being rather attractive, the wrap seems very serviceable.

Next, I shall try doing this style with larger diameter cords to see how that changes the feel of the grip........and if I'm feeling adventurous, maybe using two different colours in the same wrap.
